A funny thing happened as U.S. motorists were pursuing their love affair with SUVs: high gasoline prices and the Iraq war suddenly made gas-electric hybrids chic, according to Bloomberg News. Toyota Motor Corp. and Honda Motor Co. say they can't build enough fuel-efficient hybrids to satisfy consumer demand. In a U.S. automotive market that was down 4.4 percent in the first quarter from 2002, few other models are encountering this problem -- even other fuel-efficient models that are selling well, Bloomberg News said. The price of unleaded regular has been the motivation for some motorists, according to Bloomberg News.
